CVE-2026-31814: Rust Panic On Checked Math
Using `.expect()` or `.unwrap()` on the result of a checked arithmetic operation (e.g., `checked_add`, `checked_sub`) causes a runtime panic on overflow/underflow. When processing untrusted input, this leads to Denial of Service (DoS) due to reachable assertions. Handle the error gracefully using `.ok_or(...)?` or a `match` statement.
